To all whom it may concern:-

Be it known that I, JOHN H. MANNING,

' a citizen of. the United States, and a residenii of the borough of-Brooklyn, in the county of Kin in the city .and State of New; York, nited States of, America, have'in-f vented certain new and useful Improve-l 'ments in Pipe-'Flanging Machines, of which the following is a specification.

, My, invention. relates to pipe fianging ma chinesandits object is to im rove upon ma-' chines. of this character an to provide a simple and efiicient apparatus for forming flanges on'the ends of pipe of wrought steel or other metal.

I will describe my invention i i the .-follow-; ing specification and point out the novel features thereof in the appended claims.

Referring to the drawings, Figure 1 is a sectional. side elevation 'of a machine em-' bodying my invention. Fig.- 2 is an end elevation of apipe rest, a detail of this ma chine, and Fig. ',3, is another detail, a stop bracket. Fig. 4 isja plan view, and Fig.5 an end elevation of my improved machinel;

. In Fig. 6' I haveshown; a-sectional end ele-a vation of the machine, the section of figure being taken on the line 6- 6 of Fig. 1:

F10'. 7 is a sectional end elevation througlr' b the line 7-7 of Fig. 1 looking in the opposite direction. Fig. 8 is a cross-section. through one of the forming molds. Fig. 9 shows certain parts of the apparatus and the end-portion-of a pipe in sectional elevation and on a somewhat enlarged-scale in the relative positions they assume at the beginning of'the operation. Figs. 10, 11, 12, 13

and 14 are views of similar parts in different relative positions and illustrate the opera- ,tion of the mach ne.

. Like characters'of reference designate corresponding. parts inall of the figures;

l0 designates the baseof the machine upon which its various parts are mounted. Se

owed to this base is a pipe-rest 11 which comprises a sta'ndin which are adjustably helda pair of rollers 12. This pipe rest itself may be moved longitudinally along theframe and secured thereto in desired positions.

13' 's a carriage slidably mounted u on the base 10, a portion of which forms a ongitudi'nal tracktherefor. 14 is a iston rod which connects this carriage wit a iston within a cylinder 15. One end of this cylinderis connected with the base of the machine. The -piston and piston rod are arranged to be actuated by fluid pressure manually controlled. Bymeans of this arrangement the carriage 13 and its associated parts may be moved back and forth a limited amount along the tracks which are formed by the base 10. To the carriage 13-is bolted a stander bracket 16. The upper portion of this bracket is formed tofitloosel under a pipe and to extend up at either si e of it.

It is clearly shown in Fig.3.

17 is a die or forming mold clamp which is rigidly secured to the carriage 13 or its base is an integral part thereof. This clamp is made in two parts, a baseand a cap, which are pivoted together at 18 and arranged to 'be tightened by a bolt and nut at 19.

20 designates a forming mold which is circular inform but-cut diametrically into a lower half which is held in the base of the mold clamp 17 and an upper half held in the 'cap of this clamp by means of set'screws'21.

A rotary, disk 221m the end of a shaft 23 is supported in-pedestal bearings 24, 251- 'ujsted by means of set screws 33, '33. In each of the blocks is supporteda transverse cylindrical roller 34. The outside surfaces -of these rollers are in alinement with each other and are at substantially right-angles to the axis of the shaft 23. Ap1n35 near its inner end. On this pin-is a permanent roller 36, the forward edge of which is chamfered or founded as shown, and its rear edge is arranged to overlap the roller- 34. On the otherblock is a similar pin 37 on which is a removable flarin roller 38 which extends over the face of the roller '34 in this block. During. the process of flange-forming, this roller is removed and a e blocks31, 31. Between these blocks is a pro: jects from the. face of one of the blocks smaller roller 39 which extends back of roller 34 is preferably substituted therefor. 50 designates a pipe upon the end of which the flange is tobe formed.

51 is a strap collar which fits tightly .around the outside of the pipe. This strap is made in two parts fastened together by bolts and nuts 52, by means of which it may be securely affixed to the pipe. The first part of the operation is to securely fasten this collar to the pipe with its edge which isaway from the end of the pipe, at a desired distance from that end of the ipe which is to be formed into a flange. I the pipe is of wrought steel or similar metal this end of it is then heated, after which it is so placed in the machine that its end projects through the forming die or mold, 20, and that the collar 51 abuts against the face of the stop-bracket 16. The die or mold is made in halves and its clamp so con' structed that it may be opened tofacilitate this part of the operation. The clamp is now closed and the die tightened by means of the bolt and nut at 19. The other part of the pipe will be supported on the pipe rest 11. All of the parts are so adjusted that the pipe will be held with its axis in alinement with the axis of the shaft 23 and the parts will be in some such relative positions as those in which they are shown in Fig. 9. The operator now forces the carriage toward the rotating disk 22 and as the bracket 16 is in engagement with the collar 51 the pipe will move with it. Its heated end is then forced against the flaring roll 38 which bends it outward into some such form as that in which it is shown in Fig.

for. Fig. 11 shows the parts ready for the.

next step of the process of treatment. Again the carriage and pipe are forced toward the rotating disk. This time all of the rolls 34, 34, 36 and 39 will act upon the pipe as shown in Fig. 12 and force its end against the forming mold. A flange of desired shape and size will thus be formed. But in order to perfect the flange and to increase its strength the process is carried on further. The carriage is a ain withdrawn and the mold 20 is loosene so that the flan ed end of the pipe may be moved through t e mold or die into some such which it is shown in l ig. 13. A bar or wedge 53 is then thrust between the collar 51 and the bracket 16, the mold is tightened, and the carriage is again advanced toward the rollers in the rotating disk. The metal will now be crushed between the mold and the rollers into the position shown in Fig. 14. This will result in upsetting the metal at the end of the pipe and at the angle beosition as that in" tween the pipe and the flange so as to increase its density and its strength. While the roller 39 is preferably substituted for .the flaring roller 38 in order to balance the side pressure produced by the roller 36, the transverse rollers 34 are largely if not solely depended upon for upsetting the metal at the end of the pipe and the roller 36 may alone be relied upon to keep the inside diameter of the end of the pipe to size by preventing the metal from being forced inwardly. In this case it is only necessary to remove the roller 38 after the first step in the flanging process is completed. Before the pipe is taken out of the machine I premove the pressure of the rollers, to loosen the inold and to remove the bar 53. Then thepipe is partially rotated so that the rear of the flange will come in contact with different portions of the mold than those against which it was formed, the mold is tightened and the carriage is again forced toward the rollers. Thus a finish pressure is applied which trues up the flange. B carefully setting the position of the collar 51 at the beginning of the operation the finished flange will be of the desired thickness and diameter. The spring 32 cushions the strain on the rollers 36, 38 and 39. In small pipes the roller 36 is dispensed with, but when it is used in conjunction with the roller 39 the pressures on these rollers is balanced and the spring allows them to move in toward the center of the disk when any roughness such as a seam on'the inside of a pipe is first met. Such protuberance will be rolled down, however, during the process of flange-forming. It h s been noted that the roller 36 overlaps one of the rollers 34; and that the roller 39 runs past the end of the other roller 34. By this construction the end of the pipe is left with a sharp clean edge.

-When flanges are formed with this apparatus on the ends ofpipes of some metals such as brass or copper it is not necessary to heat the metal.

It is only necessary, in order to carry out my invention, to impart a relative rotation between the pipe and the forming rollers.

desired.

The pipe flange formed by this process is extremely strong. It is also of sufiiciently large diameter to make it very effective in ipiaws forming various kinds of pi e joints. The fiber of the metal is nowhere bent over at a smaller angle than a right-angle. The flange is formed of the integral end of the pipe without any of its portions being folded together and welded so that in all places its grain or fiber is continuous. At the corner of the flange the cross-section of the metal By-the term mold I have reference to' any suitable tool or device for accomplishing the dcsired'function and my invention is not unnecessarily limited to a circular mold or a toolof any specific form.
